EDGAR M. SENSENEY, OF ST. LOUIS, MISSOURI.

BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 279,448, dated Application filed December 20,1882.

T0 all whom it may concern:

Be it known that I, EDGAR M. SENsE EY, of St. Louis, in the State of Missouri, have invented a new and Improved Bicycle-Bell, of which the following is a full, clear, and exact description.

My invention consists of an alarm or signal bell for bicycles, having a novel and simple contrivance of the clapper by which to be operative or inoperative, the said contrivance being simple, and comprising but few parts to construct and keep in repair, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in

which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan or top view of myimproved bicycle-bell. Fig. 2 is partly a side elevation and partly a sectional elevation. Fig. 3 is a side elevation, and Fig. 4 is a detail of the clamping device by which the bell is to be attached to the machine.

I take a gong-bell,a, and attach a bow-spring,

b, by fastening the same to the crown of the gong by a screw, 0, which is fitted through a hole in the center of the spring, and to each end of said spring I attach a hammer, d, taking care to attach said hammers at such distance from the center that they will spring over the edge e and catch and hold thereon, as represented in Fig. 2, when the spring is pressed by the operator against the sides of the gong, between the hammers and center, so that the hammers will not become detached by the shaking and jarring of the machine, thus rendering the bell inoperative until the hammers are sprung off again by the operator, when the jarring of the June 12, 1883.

(Model.)

machine will instantly cause the hammers to sound the bell.

The simplicity of the contrivance is obvious. There are no parts except the attaching-screw to be kept in order, and it is plain that if once properly fitted the screw is not very liable to work loose.

The gong will be attached to a standard, g, to be fastened to any bar of the machine by a clamp, h, and screws i, as other bells are. The spring may consist of a bow, as here shown, with a hammer at each end, which I prefer; but it may of course only form part of saidbow with one hammer.

It may be stated that probably the best place to attach the bell is on the upright lever of the brake, and it should be arranged so as to set the spring I) upright that is, to swing vertically.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a gong-bell, of a spring-hammer secured to the outside thereof,

and adapted to be vibrated by the jarring of the machine, to strike the bell and to be sprung over the edges of the same when not required for use, substantially as herein shown and described.

2. The combination, with the gong-bell a,-of the bow-spring 12, secured at its center to the outside of the gong, and provided with a hammer, d, at each end adapted to be sprung under the edge of the gong, substantially as herein shown and described.
